The problem with reuse of any O-ring is the same as an original  
installation. It is quite possible to slice the OD of an O-ring on a sharp  edge 
during the dual installation (inner and outer). It is also possible to  damage it 
while removing it. I would not reuse an O-ring if I have to remove it  from 
the tube. If the tube is remaining captured in the head, and everything is  
clean and easy to inspect, just re-lube them and re-install the tube. But 
if you  have to muscle the O-ring off either end of the tube, you are asking 
for a tear  or scar. In that case replace them
